Background: Acrylic resin bases attract stains and odor producing organic and inorganic deposits. The use of chemical denture cleanser soaks is the most popular method of denture cleansing. Aim: To compare the efficacy of 2 different denture cleansers in removing tea, coffee, turmeric and paan stains from heat cured clear acrylic resins. Materials and Methods: Two hundred heat cured clear acrylic samples were prepared. The samples were divided into four groups and stored in tea, coffee, turmeric and paan at 37C for 10 days. Stained samples were subjected to immersion in the commercially available denture cleansers sodium perborate (Clinsodent), sodium hypochlorite (VI-Clean) and distilled water (control). Optical density (OD) values were measured before and after 20 minutes and 8 hours of immersion in the cleansers. The data were analyzed statistically using Fischer's test (one way ANOVA) and multiple comparisons were done by Bonferroni test. Results: Both Clinsodent and VI-clean were found to be least effective in removal of coffee stains and best for removing turmeric stains. Conclusion: It is necessary for the dental professional to ensure that the denture wearing public knows how to select the appropriate denture cleanser so as to improve denture home care protocol.
